Hello, I tried the latest zeppelin release (binary with all interpreters), and in order to make the flink interpreter work in non-local mode, i had to copy all scala libraries from another interpreter to the flink interpreter.
After trying to connect to an existing flink cluster i got zeppelin_1 | Exception in thread "pool-1-thread-2" java.lang.NoClassDefFoundError: scala/collection/Seq zeppelin_1 | at java.lang.Class.forName0(Native Method) zeppelin_1 | at java.lang.Class.forName(Class.java:264) zeppelin_1 | at org.apache.zeppelin.interpreter.remote.

Thanks, greetings, Frank
